The SVT exhaust sounds pretty good on the SEs. I'm sure there are a few video clips around. The best mod for the SVT exhaust is replacing the resonator with a straight through magnaflow component. It's the poor man's mod, but sounds really good.
I, personally bought the svt exhaust from a guy who already replaced the stock resonator with a straight pipe. At first, I was amazed, but soon the drone and rasp got to me. In my opinion it's too loud and annoying. I was thoroughly impressed when I put the magnaflow resonator in place. It took about a week to get it used to, but thereafter has sounded sweet. Just some things to keep in mind. The svt exhaust is very nice, but is a bit too quiet with the stock resonator, in my opinion.
